The present invention relates to a method and an apparatus for employing an embedded subscriber identity module (hereinafter referred to as eSIM) to apply a policy such as a subsidy policy to, activate, deactivate, add to, update, and delete a user profile in a mobile communications network. The present invention enables a mobile device to determine whether to host the policy of a new service provider when it changes the present service provider or to perform a lock for prohibiting the policy change, and to change the profile related to the determination. The present invention also enables a mobile device to replace the policy related to the service provider by applying the policy, or to employ eSIM so as to activate, deactivate, revise, add, or delete the rules of the policy related to the service provider. The present invention provides various examples of hosting and applying the policy and various examples of activating, deactivating, revising, adding, deleting the policy rules so as to make eSIM identify the subscriber as the existing subscriber identity module. The invention also enables the device or eSIM to be reused when changing the service provider throughout the life cycle thereof without limiting the use of eSIM to a single service provider. The invention also provides a method for locking the policy applied per service provider, and the use of eSIM when changing to another service provider by the policy per service provider. The present invention also provides a method for checking the criteria of decision and verifying the power of decision when administering the policy rules and eSIM through deleting, adding, revising, activating, and deactivating the profile management plan and policy rules by applying the service provider's policy.
